To effectively support dynamic provisioning, an adaptive infrastructure which enables host-swapping and fault tolerance is necessary. Addressing this challenge, we propose a Highly Available Dynamic Deployment Infrastructure (HAND), based on the Java Web Services Core of Globus Toolkit 4. HAND provides capability, availability and extensibility for dynamic deployment of Java Web Services in dynamic grid environments. We identify the factors that can impact dynamic deployment in static and dynamic environments. We also present the design, analysis, implementation and evaluation of two different approaches to dynamic deployment (service level and container-level). We also examine the performance of an alternative data transfer protocol for service implementations. The results demonstrate that HAND can deliver significantly improved availability and performance relative to other approaches.
